Strong base is dissolved in 625 mL of 0.400 M weak acid (Ka 4.48 x10) to make a buffer with a pH of 4.08. Assume that the volume remains constant when the base is added Calculate the pKa value of the acid and determine the number of moles of acid initially present. ncorrect. Use the volume and concentration in the question to find moles. Number Number pK,434 2.5 mol HA Molarity is the number of moles per liter When the reaction is complete, what is the concentration ratio of conjugate base to acid? Number НА How many moles of strong base were initially added? Number mol OH
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
